Harriet Tubman secretly worked as a Union spy

Most Americans know Harriet Tubman for her leadership of the Underground Railroad, but during the Civil War, she also became a Union scout and spy in South Carolina. Working with Colonel James Montgomery, Tubman gathered intelligence from enslaved people living behind Confederate lines near the Combahee River .

In June 1863, Tubman helped lead the Combahee River Raid, guiding Union gunboats through Confederate waters filled with hidden mines. The operation freed more than 700 enslaved people and made Tubman the first woman known to lead a major U.S. military mission.

Julia Child worked for the U.S. intelligence agency

Before becoming television’s most famous chef, Julia Child joined the Office of Strategic Services, or OSS, in 1942 during World War II. The OSS later evolved into the CIA. Too tall to enlist in the Women’s Army Corps, Child instead classified files and overseas communications in Asia.

One of her strangest assignments involved helping researchers develop shark repellent for Navy explosives and emergency rescue kits . The repellent used copper acetate and black dye to create an odor similar to a dead shark.

Benjamin Franklin conducted unofficial spy work in Europe

Benjamin Franklin was more than a scientist and Founding Father. During the American Revolution, he quietly acted as an intelligence organizer while serving as ambassador to France beginning in 1776 . Franklin cultivated secret alliances, intercepted information, and used coded correspondence to support the colonies’ fight against Britain.

Operating from Paris, Franklin built relationships with French officials and helped persuade France to support the American cause with money, troops, and naval power. Historians consider his diplomatic intelligence efforts essential to the American victory at Yorktown in 1781 and eventual independence.

Louisa May Alcott published thrillers under another name

Louisa May Alcott became a literary icon after publishing Little Women in 1868, but few readers knew that she had already written sensational thrillers under the pen name "A.M. Barnard." These stories featured revenge, hidden identities, forbidden romance, and dramatic crime plots that shocked Victorian audiences.

Alcott used a pseudonym because publishers often expected women writers to produce respectable domestic fiction. Many of her darker stories remained forgotten until scholars rediscovered them in the 1940s. Today, titles like Behind a Mask reveal a far more rebellious side of the beloved author.

Maya Angelou worked as San Francisco’s first black female cable car conductor

Long before becoming a celebrated poet and author, Maya Angelou made history in San Francisco during the 1940s. At only 16 years old, she applied repeatedly for a conductor job on the city’s cable cars after seeing an advertisement that excluded Black applicants .

Angelou refused to give up despite repeated rejection. She eventually became San Francisco’s first Black female cable car conductor in 1944. Years later, she described proudly wearing the blue uniform while working long shifts across the city before launching her writing and civil rights careers.

Dr. Seuss created classified wartime propaganda films

Before writing Green Eggs and Ham and The Cat in the Hat , Theodor Geisel, better known as Dr. Seuss, worked on wartime propaganda during World War II. Between 1943 and 1945, he joined director Frank Capra’s Signal Corps unit to produce military training films for American soldiers .

Geisel also drew political cartoons supporting the Allied war effort and criticizing fascism. Some of his films were classified during the war because they contained military training material. His animated work helped explain battlefield strategy and morale issues to thousands of U.S. troops overseas.

Babe Ruth once played an entire game with a fever over 102 degrees

In 1925, Babe Ruth became seriously ill during spring training and collapsed while traveling by train . Newspapers nicknamed the incident "the bellyache heard around the world." Reports from the time described Ruth suffering from a fever above 102 degrees while still insisting on returning to baseball activities.

Despite his condition, Ruth’s determination became part of baseball legend. The illness hurt his performance during the 1925 season, when the New York Yankees finished seventh in the American League. Even so, Ruth rebounded quickly and helped lead the Yankees to championships in later years.

8

Harry Houdini worked with police departments

Harry Houdini’s famous escape acts fascinated police departments across America and Europe in the early 1900s. Officers regularly challenged him to escape from handcuffs, prison wagons, and locked jail cells. Houdini often invited local police to inspect restraints before his performances began.

Beyond entertainment, Houdini also worked closely with law enforcement to expose fraudulent mediums and fake spiritualists during the 1920s . Using his knowledge of locks, hidden compartments, and deception, he publicly demonstrated how many supposed supernatural tricks were actually carefully staged illusions.

9

Frank Lloyd Wright hid a private apartment inside one of his buildings

Architect Frank Lloyd Wright secretly maintained a private apartment inside his famous Oak Park Studio near Chicago, Illinois. Built in the 1890s, the studio served as both his workplace and personal retreat while he designed many of his early Prairie-style homes across the Midwest.

The hidden living quarters allowed Wright to work late into the night and host select guests away from public attention. The building itself became one of the most important centers of American architecture, producing groundbreaking residential designs that influenced modern architecture around the world.

Muhammad Ali quietly funded humanitarian causes for years

Muhammad Ali’s boxing fame often overshadowed his enormous charitable work. For decades, Ali quietly donated money to hospitals, food programs, children’s charities, and international humanitarian efforts . Friends and family later revealed that many of his contributions were intentionally kept private.

In 1990, Ali traveled to Iraq during tensions leading up to the Gulf War and helped secure the release of 15 American hostages. He also supported global relief organizations and Parkinson’s disease research after his own diagnosis. In 2005, President George W. Bush awarded Ali the Presidential Medal of Freedom.

Josephine Baker

Josephine Baker was the first Black woman to star in a major motion picture , the 1927 French silent film Siren of the Tropics . During her early career, Baker was among the most celebrated performers to headline the revues of the Folies Bergère in Paris. Her performance in the 1927 revue Un vent de Folie caused a sensation in the city. Her costume, consisting only of a short skirt made of artificial bananas and a beaded necklace, became an iconic image and a symbol both of the Jazz Age and the Roaring Twenties.

Baker was celebrated by artists and intellectuals of the era, who variously dubbed her the "Black Venus," the "Black Pearl," the "Bronze Venus," and the "Creole Goddess." She aided the French Resistance during World War II, and after the war, she was awarded the Resistance Medal by the French Committee of National Liberation, the Croix de Guerre by the French military, and was named a Chevalier of the Legion of Honour by General Charles de Gaulle.

Rudy Vallée

Rudy Vallée was the first male singer to rise from local radio broadcasts in New York City to national popularity as a "crooner." He had a thin, wavering tenor voice and seemed more at home singing sweet ballads than jazz songs. But his singing, saxophone playing, and the innovative arrangements he wrote for his band attracted the attention of a rapidly increasing number of listeners, especially young women.

Singers needed strong voices to fill theaters in the days before microphones. Crooners had soft voices that were suited to the intimacy of radio; the microphones, in this case, promoted direct access to "a vulnerable and sensuous interior," or, in other words, "a conjured intimacy." Vallée was one of the first celebrity radio vocalists.

Bobby Darin

Bobby Darin was an American teen idol and, later, an adult crooner who, in 1958, co-wrote and recorded his first million-selling single, "Splish Splash," followed by "Dream Lover" and his covers of "Mack the Knife" and "Beyond the Sea," which brought him worldwide fame.

In the early 1970s, his health was beginning to fail due to a weak heart. The knowledge of Darin's vulnerability had always spurred him on to use his musical talent while still young. Darin died in 1973 at the age of 37 in a hospital recovery room after having open-heart surgery in Los Angeles.

Keely Smith

American jazz and popular music singer Keely Smith performed and recorded extensively in the 1950s with her then-husband Louis Prima , and throughout the 1960s as a solo artist. The couple were stars in the entertainment business, including stage, television, motion pictures, hit records, and cabaret acts.

They won a Grammy in 1959, its inaugural year, for their smash hit, "That Old Black Magic," which remained on the charts for 18 weeks.

5

The Ink Spots

The first band on the list, the Ink Spots was an American vocal pop group who gained international fame in the 1930s and 1940s due to their unique musical style, which predated rhythm and blues and doo-wop .

On January 12, 1939, the Ink Spots recorded "If I Didn't Care," one of their biggest hits, selling over 19 million copies and becoming the 8th-best-selling single of all time. Since they disbanded in 1954, there have been well over a hundred vocal groups calling themselves "The Ink Spots," with and without any original members of the group.

Ella Fitzgerald

A frequent collaborator of the Ink Spots, Ella Fitzgerald was a singer, songwriter, and composer, sometimes referred to as the "First Lady of Song," the "Queen of Jazz," and "Lady Ella." She was noted for her purity of tone, impeccable diction, phrasing, timing, intonation, absolute pitch, and a "horn-like" improvisational ability, particularly in her scat singing.

Outside her solo career, she recorded music with Louis Armstrong, Duke Ellington, and the aforementioned Ink Spots. These partnerships produced songs such as "Dream a Little Dream of Me," "Cheek to Cheek," "Into Each Life Some Rain Must Fall," and "It Don't Mean a Thing (If It Ain't Got That Swing)."

Bing Crosby

A one-man orchestra, Bing Crosby was a singer, actor, television producer, radio personality, and businessman. The first multimedia star , he was one of the most popular and influential musical artists of the 20th century worldwide.

In 1948, American polls declared him the "most admired man alive," ahead of Jackie Robinson and Pope Pius XII. That same year, Music Digest estimated that Crosby's recordings filled more than half of the 80,000 weekly hours allocated to recorded radio music in America.

Crosby is one of 33 people to have three stars on the Hollywood Walk of Fame , in the categories of motion pictures, radio, and audio recording.

Perry Como

Perry Como was an American singer, actor, and television personality who sold over 100 million records worldwide and pioneered a weekly musical variety television show. His weekly television shows and seasonal specials were broadcast around the world. He recorded primarily vocal pop and was renowned for his recordings in the intimate, easy-listening genre pioneered by our newly acquainted friend, Bing Crosby.

In the official RCA Records memorial in Billboard magazine, his life was summed up in these few words: "50 years of music and a life well lived. An example to all."

Nina Simone

A bigger-than-life figure, Nina Simone was a singer, songwriter, pianist, composer, arranger, and civil rights activist whose piano playing was strongly influenced by baroque and classical music, and accompanied by expressive, jazz-like singing in her contralto voice .

Early in her career, Simone played piano at a nightclub in Atlantic City, where she was told that she would have to sing to her accompaniment. This effectively launched her career as a jazz vocalist. Simone also became known for her work in the civil rights movement during the 1950s and 1960s, and she later fled the United States and settled in France following the assassination of her friend Martin Luther King Jr. in 1968.

Screamin’ Jay Hawkins

The closer of this list is one of the most colorful characters in American music. "Screamin' Jay" Hawkins was a singer-songwriter, musician, actor, film producer, and boxer, best known for his powerful, shouting vocal delivery and wildly theatrical performances with macabre props onstage, making him an early pioneer of shock rock.

Screamin’ Jay’s most successful recording, "I Put a Spell on You," was created when the entire band was intoxicated during a recording session where "Hawkins screamed, grunted, and gurgled his way through the tune with utter drunken abandon." The resulting performance became his greatest commercial success and reportedly surpassed a million copies in sales.

1

New York, The Empire State

Probably the most famous and recognizable state nickname, no one really knows who was the first to call New York State the "Empire State", but everyone agrees on the reason for the nickname. The state of New York has always been one of the richest, most developed, and strategically important territories in America , a powerhouse akin to an empire. George Washington himself had described it as "the seat of the Empire" in 1785, and many believe that these words were the source of the nickname.

2

Indiana, The Hoosier State

Another instantly recognisable nickname, the origin of the term ‘Hoosier’ is also widely debated. Believed to have emerged in the 1830s, some say that it is a deformation of the phrase "Who's here?". No matter its actual origin, the term was popularized by John Finley's 1833 poem "The Hoosier's Nest" , a description of rugged but welcoming Indiana pioneers, and it became a source of pride for the state, so much so that ‘Hoosier’ was officially adopted as a demonym by the state of Indiana in 2017.

3

Delaware, The First State

Delaware was not the first colony to exist or to become a state. In fact, Delaware wasn’t even a colony: it was technically part of Pennsylvania. The ‘first’ referenced in the nickname alludes to Delaware’s role in the ratification of the U.S. Constitution , a task that took time and political compromise, as several states had concerns about the document and its articles. But while it took nearly two years for all the states to ratify the Constitution, it took less than three months for Delaware to do so unanimously, setting a precedent for other states.

4

Virginia, The Old Dominion

Probably the oldest state nickname still in use, Virginia’s ‘Old Dominion’ nickname has existed for more than 400 years. The first English colony in America, Virginia was also the main colony to remain faithful to the monarchy during the English Civil War , supporting the exiled King, inviting him to take refuge in their territory, and resisting the siege from the Parliamentary fleet for a long time. After the restoration, King Charles II conferred the colony the title of ‘dominion’ —similar to a kingdom in rank— and affectionately called it "the most Ancient Colloney and Dominion."

5

Oklahoma, The Sooner State

Although it is now used as a symbol of a competitive and pioneering attitude, the term ‘Sooner’ was not always seen as positive. During the Land Rush of April 22, 1889, the U.S. government opened a territory —freed by the forced displacement of thousands on ative Americans— for pioneers to take. At noon, a bugle would signal that settlers could enter and claim areas of land. However, several pioneers broke the rules, entering the territory ‘sooner’ , before the signal. Initially a pejorative nickname, the people of Oklahoma eventually owned the term as a symbol of their ‘can-do’ attitude.

6

Connecticut, The Constitution State

Unlike what many people think, Connecticut’s nickname is not related to the U.S. Constitution. In fact, the ‘constitution’ referenced in it predates the American Constitution by more than a century. Unlike other colonies, established by royal charters, the Connecticut Colony was established through The Fundamental Orders , a document delineating a representative government based on "the free consent of the people". The Fundamental Orders are considered to be the first written constitution in Western modern history, a fact that gave Connecticut its nickname.

7

Tennessee, The Volunteer State

Out of the many things that showcase Tennessee’s patriotism, none is as old or as well-documented as its volunteer vocation. Starting during the Revolutionary War, with the Appalachian Overmountain men volunteering to fight during the Battle of King's Mountain, Tennessee’s men's willingness to volunteer as soldiers became known during the War of 1812 , with hundreds fighting under Andrew Jackson’s command and earning Tennessee the name of the Volunteer State. To further solidify it, when President James K. Polk asked Tennessee for 2,800 volunteers during the Mexican-American War of 1846, the state responded to the call by sending 30,000 volunteer troops.

8

Vermont, The Brave Little State

A relatively more recent nickname than others in this list, the description of Vermont as a ‘brave little state’ dates back to 1928. After a flood in 1927 resulted in nearly 100 casualties and millions of dollars in damages, President Coolidge, a Vermont native, visited the state to assess the situation. Coolidge, often seen as calm and taciturn, gave an emotional speech praising the efforts and the resilience of his fellow Vermonters , and their ties to a land that gave them sustenance but posed the hazard of natural disasters. Coolidge ended his speech by acknowledging the generosity of the people of "this brave little state of Vermont", a phrase that became so popular that it was later inscribed in the Vermont State House and became a common nickname for the state.

9

Wisconsin, The Badger State

Though badgers can be found across Wisconsin, they are far less common than one would think, especially considering the state’s nickname. But this nickname has little to do with real badgers and much to do with people behaving like a badger. In the 1820s, prospectors all over America travelled to Wisconsin to look for lead ore. Working all day in the mines and lacking proper housing, the miners usually ended up living in the mines or digging holes in the hillsides to serve as shelter , which led people to compare them with burrowing badgers. Eventually, the ‘badger’ nickname became a symbol of the tenacity of the miners, and a point of pride for all Wisconsinites, who campaigned in 1957 to officially adopt the badger as their state animal.

10

Nebraska, The Cornhusker State

Though this famous nickname for Nebraska has ties with the agricultural identity of the state, it actually originated in the world of college football. Before 1900, the University of Nebraska football team had used several nicknames, such as Bugeaters, Tree Planters, or Rattlesnake Boys. Following a rough patch and wanting to give the team a new direction, sportswriter Charles Sherman suggested the nickname ‘cornhusker’ as a homage to the traditional corn husking done by hand by the Nebraska settlers . The name caught on and was eventually made extensive to all Nebraskans, being officially adopted by the state in 1945.
